Chip Tuning

The first motor modification I did was adding a performance chip to the car. Out all the bolt-on performance modifications you can do, the chip upgrade is one of the most significant improvements over the factory setup you can buy.

The modification involves removing the ECU for the car and prying the factory chip out of the socket and replacing it with the re-tuned chip. A simple install if you've ever handled electronics, or you can have a competant shop to the swap in about 15 minutes. The gains are usually made by an advancing of the ignition and altering of the fuel-air ratio and engine mapping.

I started off with the Neuspeed chip based on reputation. While many people have had good experiences with Neuspeed, I have not. I found their chip to deliver a marginal performance gain over the factory chip (at least in my car).

On a visit to Advanced Motorsport Solutions in Costa Mesa, one day, they talked me into giving their EPROM a try. So, I went for it. I was truly amazed! The difference was apparent and immediate. Gains from 3,000rpm - 5,000rpm. This was definitely by the seat-of-the-pants test, since I have never dyno'ed it, but the gains were noticeable none the less.

There are many manufacturers of tuned chips out there. It can be difficult to make a choice, if this is your first time. If you ask others about which chip to buy, it can turn into a religious debate. Lots of people have very strong opinions when it comes to which chip is "best". Some of the more vocal are the Garret chip customers who take any chance they get to promote their chip. I have never used the Garret chip, so I cannot say one way or the other who's chip is best. My chip from AMS satisfies my needs.

I have seen many performance graphs charting the different chips on the market and they all deliver similar performance gains. My advice would be to find a company that offers good customer service and a guarantee on their product. Most of the companies offer a competitive upgrade price for users of other chips.

You'll want to use 92 Octane (Premium) grade fuel in your car after upgrading to a chip to avoid pinging due to the advanced ignition.
